demand on the ground that 'Walky' is a fixed wireless A phone WWL(F), having portability as its feature and hence could not be classified as WWL(M). Appellant raised the dispute before Telecom Disputes Settlement and Appellate Tribunal wherein it was held that 'Walky' calls attracted ADC under the regulatory regime. Hence the B present appeal.

¶24

¶25

Appellant contended interalia that the respondent had no authority to impose ADC liability unilaterally on the appellants by classifying the instrument as a mobile phone; that the demand was misconceived as the dispute^c regarding its classification was subjudice before the authority; that 'Walky' as an instrument is portable, not mobile and therefore could not be classified as WWL(M); that Telecom Regulatory Authority of India (TRAI) by the Circular dated 4.3.2003 has reclassified 'Walky' as WLL(M) D and thereby has amended the terms and conditions of UAS Licence and Telecommunication Interconnection Usage Charges Regulation 2003 (IUC Regulations).

¶26

Respondent-BSNL contended interalia that there E was no unilateralism in the demand made by BSNL, as the same was made only after the TRAI and the Department of Technology (DoT) had issued the Circular dated 4.3.2003 and Directives dated 23.3.2005 and 26.8.2005, respectively; that compliance of the Order/ F Directive of DoT dated 26.8.2005 by the appellant, indicates that even according to the appellants, ADC was payable in respect of the service, i.e., WLL(M) and, therefore, it was not correct to say that ADC could not be charged without change in the conditions of licence or 2003 Regulations.

¶41

1.2 Directive dated 4.3.2005 by Telecom Regulatory Authority of India (TRAI) was issued to all access B providers. The said directive came to be issued as it was brought to the notice of TRAI that new terminals were being deployed by access providers which terminals do not have any fixed network access point physically located at the address of the subscriber. In the said Circular, TRAI c noted that fixed wireless services were required to be provided through fixed wireless terminals with the location of the network access point being fixed and with the end-user terminal being connected to it. That, it had been brought to the notice of TRAI that new terminals were ·D being deployed by certain access providers which did not possess fixed network access point physically located in the premises of the subscriber. Therefore, by the said Circular, TRAI directed the service providers to strictly ensure that the terminal used for fixed wireless services E^{shouldstrictlycomplywithpremisesspecification} restriction, i.e., to the premises of the subscriber. The Circular dated 4.3.2005 stood followed by letters from DoT dated 23.3.2005 and 26.8.2005. [Para 38] [356-F, G; 357-A-D]

¶42

1.3 The Circular dated 4.3.2005 issued by TRAI is F clarificatory and not amendatory. In the Circular, TRAI has used certain technological terms generally used in telecommunications like 'network access point', 'end-user terminal' and 'fixed network access point'. These terms find place in the generic requirement formulated as far G back as 1996. They also find place in the Principles of Wireless Access formulated by ITU-RCA. Keeping in mind the definitions given both in the technical references as well as in the principles of wireless access formulated by ITU-RCA, it is clear that Premises Specific Restriction H^{("PSR") isnot something new which stood evolvedfor}

1.4 Broadly FWA is called WLL(F). The UAS Licence refers to three types of wireless services, namely, full mobility, limited mobility and FWA. As stated, in FWA, the location of the end-user (Walky) and the network access point (antenna connected to the end-user) are both fixed C whereas in the case of mobile wireless access, the location of the end-user is mobile. WLL(M) is a hybrid between FWA and MWA. Wireless access may be considered from many perspectives. [Para 40] [358-B, C]

1.5 The main purpose of FWA [WLL(F))] is to provide D network access to buildings through exterior antennas communicating with Central Radio Base Stations. In FWA, users in a building are allowed to connect to the network with conventional in-built networks. FWA is a service. It is intended as a cheap cable replacement, without additional E features. Wireless systems differ depending upon the amount of mobility that they allow for the users. FWA system is a derivative of cordless phones. In FWA there is no mobility of the user devices. This is where the concept/ principle of PSR emerges. There is a difference between F mobility and portability. A terminal may be portable but every portable device is not mobile. The concepts mentioned in Circular dated 4.3.2005 issued by TRAI exist in telecommunications right from 2001. The said Circular merely clarifies and brings out the concept Premises Specific Restriction (PSR). [Para 40] [358-D, E, F, G] G

A Circular dated 4.3.2005 'Walky' has been reclassified as WLL(M) for the first time by TRAI. If the concept of FWA [WLL.(F)] embodies PSR and that too from 2003 then it is clear that the said Circular dated 4.3.2005 is clarificator1. It does not alter the terms and conditions of the licence. B^{FWAisoneof thewirelessservices contemplated by} UAS Licence which is dated July, 2003, therefore, much prior to circular dated 4.3.2005 these concepts were known to all access providers right from 2003. [Para 42] [359-C, D, E]

c 1.7 ADC is a levy. Its levy depends on mobility as a service feature. The numbering plan, radio frequency etc. are all important elements of a network. The numbering levels for fixed wireless services and for WLL(M) services are different. So also the numbering levels for fixed D wireless service, limited mobility service and full mobility service are different. The identification of the call whether originating from mobile or from 'Walky' or FWA has a correlation with the numbering plan which is an important element of the network of the appellant in its MSC. For E^{levy of ADC,integrity of numbering plan is very important.} [Para 43] [359-F-H; 360-A]

¶62

1.8 In the present case, TRAI has detected that the appellant is providing WLL(M) service in the garb of fixed wireless phone service (FWA) which disturbs the integrity F of the numbering plan. In the case of full mobility, the rate is different as compared to the rate in the case of limited mobility as compared to the rate in fixed wireless service. This difference in the rates is spelt out in IUC Regulation, 2003. It is for this reason that even in the clarification G issued by DoT on 23.3.2005, the access providers were warned by pointing out that the issue of mobility has implication with respect to the applicability of ADC. It was further clarified that if it is not possible for the access provider to comply with the requirement of PSR then the H^{'Walky' services shall be treatedas WLL(M) service for all}

purposes including numbering plan, interconnection A usage charges, ADC etc. This is because a separate level with allocated short distance charging area based link numbering is to be used for wireline and fixed wireless services. [Para 43] [360-A, B, C, D]

¶73

¶74

1.9 The record indicates that right from 2003, when UAS Licence stood issued, the classification was contemplated by the licensor-DoT when it categorized wireless service into full mobility, limited mobility and FWA. ADC, interconnection usage charges etc. follow that classification. IUC Regulation, 2003 imposes the statutory^c charges based on the classification in the licence. What is important in this case is that besides technological data, even as a matter of policy if there is a contract between DoT and the access provider in terms of LIAS Licence which provides for three categories, then the levy of ADC D would depend upon the service which is rendered to the user by the access provider. In the circumstances, apart from technology, this case is more on tax policy which levies ADC on services which fall in the category of WLL(M). [Para 43] [360-D, E, F, G] E

¶75

¶76

1.10 Wireless systems differ in the amount of mobility that they have to allow for the users. The ability to move around while communicating is one of the main features of wireless communication for the user. However, within that requirement of mobility, different grades exist; i.e. Fixed Devices; Nomadic Devices; and Low Mobility.[Para 44] [360-G; 361-A]

¶77

¶78

1.11 In the licence there are three types of wirelss services, namely, limited mobility, full mobility and FWA. G IUC levies the charge based on this classification. ADC is a part of IUC. ADC is also levied under IUC Regulation, 2003. In the case of 'Walky', the instrument can be put in the car, it can be carried throughout SDCA and 'Walky' calls can originate not only from the subscriber's premises H

A but it can also originate from any point in the SDCA. Because of this mobility, it is classifiable in the category of limited mobility. In the case of FWA [WLL(F)], there is no mobility of the user device. When there is no such mobility of the user device, it is similar to all wired B^{communications.Therefore,FWAiscategorizedas} WLL(F). All wired communications can also fall in WLL(F) for the purposes of levy of ADC. However, since the user device in the case in hand is mobile throughout SDCA, the services which the instrument 'Walky' offers has to c^{becategorized as WLL(M) service.Inthe present case,} the appellants were providing WLL(M) services during the above period in the garb of FWA or fixed wireless phone services and thereby they have infringed the integrity of the numbering plan. Therefore, ADC is payable by the D^{appellants for the aforesaid period, namely, 14.11.2004 to} 26.8.2005. [Para 45] [361-D-H, 362-A, BJ

¶84

1.12 Classification of services stood effected under UAS Licence 2003. Under the terms and conditions of that licence, the access providers were required to maintain E^{the integrity of the numbering plan. This was oneof the} conditions of the licence. Similarly, classification/ categorization of wireless services was done under the licence. The categorization constituted the term of the licence. As a matter of follow-up for the purposes of levy F^{of certain charges, includingADC,IUCRegulation 2003} stood enacted. Under Section 11 (1 )(b) of Telecom Regulatory Authority of India Act, 1997, the TRAI is empowered to ensure compliance of terms and conditions of licence and to fix the terms and conditions of interG^{connectivitybetween theserviceprovidersSimilarly,} under Section 11(1)(c), TRAI is also authorized to levy fees and other charges at such rates and in respect of such services as may be determined by regulations.

KAPADIA, J. The controversy in these civil appeals is: whether appellant is liable to pay Access Deficit Charges ("ADC") to BSNL for the period commencing from 14.11.2004 to 26.8.2005 in respect of its service provided under its brand c^{name "WALKY".}

¶114

Introduction:

¶115

ADC is a levy imposed by TRAI (Regulator) on the operators (service providers) to support roll out of telephones in rural areas. Since BSNL owns 99% of the rural phones, ADC D constitutes a levy for the appellant and a subsidy for BSNL. The said ADC has two parts: (i) the component of the payment to be made by the domestic service provider, and (ii) the component of the payment to be made by international long-distance service providers. The ADC regime was introduced in 2004.

¶116

¶117

In March, 1997, Telecom Regulatory Authority of India ("TRAI") Act stood enacted. The Government introduced New Telecommunication Policy ("NTP") in 1999 and proceeded to implement the said policy. By TRAI (Amendment) Act, 2000 a F^{key change came to be effected as a result of NTP,1999. The} said amendment segregated the Regulatory and Dispute Settlement norms of the original TRAI. Under the new regime, all disputes involving consumer and service provider(s) had to go to TDSAT. The said regime excluded civil courts from ruling on disputes arising out ofTRAI decisions. TDSATwas conferred G with original and appellate jurisdictions. The TRAI (Amendment) Act, 2000 defines precisely the regulatory powers of the TRAI. The said Regulator became responsible for introduction of new service providers, technical improvements, quality standards and fixing the terms and conditions of licences. One more event H needs to be mentioned. In order to separate policy making and

service provision roles of the DoT, the Government created Department of Telecom Services ("DTS"}, which was later turned into the corporate entity known as BSNL on 1.10.2000.

¶128

Under the NTP, 1999, all new cellular mobile service providers had to pay a fixed fees upon entry, and then pay a portion of their revenues to the Government. However, after August, 1999 the revenue-sharing arrangement came into effect.

¶129

¶130

Given an ambitious target to achieve a tele-density of 7%, the NTP 1999 sought to bring private players into basic c service which is the minimum facility and in which mobility as feature of a telecom service was not a part of basic service. The permissibility to provide a service is determined by the terms and conditions of a licence granted by DoT whereas obligation to pay interconnection usage charges/ADC is determined by D TRAI through its regulations framed under section 36 of the 1997 Act in conformity with the licence conditions.

¶131

By a policy decision of Government of India in 2001, basic service operators having the licence for providing fixed service were allowed to provide Wireless Local Loop Mobile [WLL(M))] service within the purview of their basic service licence.

A WLL Technology:

¶143

Before considering the contentions advanced on behalf of the appellants and BSNL (respondent no. 1 ), it would be necessary to consider certain terms used in the WLL technology.

¶144

¶145

i) Cellular Telephony

¶146

Cellular telephone is a type of short-wave analog or digital transmission in which a subscriber has a wireless connection from a mobile (terminal) to a nearby transmitter. The transmitter's area of coverage is called as a cell. In wireless telephony, a cell c is the geographical area covered by a cellular telephone transmitter. The transmitter facility is called the cell site. When a subscriber enters into an agreement with a cellular telephone service provider, he is given access to the cell system of that provider, which is local. When travelling out of the range of the D^{said cell system, the cell system can enable him to be transferred} to a neighbouring company's cell system without the subscriber being aware of it. This is called roaming service. A cellular telephone is not to be confused with a cordless telephone, which is simply a phone with a very short wireless connection to a E^{local phone outlet.}

¶147

High mobility of the users is one of the important properties of cellular telephone. The location of a user can change significantly during a call which can originate from the user or from the network. In cellular telephony a mobile user F^{communicateswith a base station.Thebase stations are} connected to MSC, which is connected to the public telephone system. The most important aspect of cellular telephony is the unlimited mobility. The user can be anywhere within the coverage area of the network (i.e., !t is not limited to a G^{**specific cell).**The user can move from one cell to another even} during one call.

¶148

Cellular telephony is different from cordless telephone. In cordless telephone, there is a wireless link between a handset and a base station which in turn is directly connected to the H public telephone system.

'""'

¶154

It is important to note that economic factors impact the A design of wireless communication systems and services. Those systems where the mobility is of value per se - e.g., in cellular telephony, the same is more expensive than wired system. For example, the per minute price in the case of cellular telephony system is higher than the landline telephone. It is competition B which may bring down the price per unit. Since 1990 many consumers and even companies have opted for cellular telephony alone cancelling in some cases wired services. On the other hand, services where wireless access is only intended as a cheap cable replacement, without additional features - c e.g., Fixed Wireless Access, the systems have to be cost effective, as the infrastructure is comparatively cheaper as compared to the infrastructure needed for wired connections.

¶155

ii) Examples of Wireless Equipments:

¶156

--!

¶157

¶158

Wireless is a term used to describe telecommunications^D in which electromagnetic waves carry the signal over the communication path. The first wireless transmitter went on the air in the early 20¹ h Century using Morse code. Later, as technology improved it became possible to transmit voices and music via wireless, the medium came to be called "radio". With E the advent of television, fax, data communication and the effective use of the spectrum, the term "wireless" has been revived. The common examples of wireless equipments in use today include cellular phones, pagers, global positioning system ("GPS"), cordless telephone sets, satellite television, wireless F LANs (Local Area Networks), global system for mobile communication ("GSM"), fixed wireless application, mobile wireless and portable wireless. Correspondingly, services are broadcasting, paging, fixed wireless access (FWA), limited mobility and full mobility etc. G

¶159

In the case of fixed wireless, the operation of wireless systems is confined to homes and offices, in particular, fixed wireless refers to equipment connected to the internet via specialized modems. In FWA, the location of the end-user terminal and network access point to be connected to end-user H

A are fixed.

In the case of mobile wireless, there is the use of wireless systems or devices aboard motorized, moving vehicles like, PCS. It also includes automotive cell phones. Unlike FWAs, in the case of mobiles the instrument is not fixed, it can be moved.

¶166

As regards portable wireless, it is battery-powered wireless device or system which operates outside the office, home or vehicle. Its operation is autonomous. The examples of portable wireless are handheld cell phones and PCS units.

¶167

¶168

All the above examples are common examples of wireless equipments in use today.

¶169

iii) Wireless Mobile Communication:

¶170

There are a variety of wireless communication systems D for transmitting voice, video and data in local or wide areas. Mobile wireless technologies provide voice and data communication services to mobile users to use cell phones, internet terminals and related computing devices.

¶171

¶172

iv) Wireless Communications Service (WCS):

¶173

WCS is radio communications that may provide fixed, mobile, radio location or satellite communication services to individuals and businesses within their assigned spectrum block and geographical areas. WCS is today capable of providing F more advanced Wireless Phone Services that would be able to pinpoint a subscriber in a given locality. WCS is today used to provide a wide variety of mobile services, including an entire family of new communication devices utilizing small, light weight; multifunctional Portable Phones and advanced devices with twoG way data capabilities. It may be noted that every mobile is portable but every portable phone need not be a mobile. It may also be noted that we are concerned with "service" to the individual business and not with the nature of the instrument.

viii) Cellular Systems and Topology:

¶192

¶193

A cell in a cellular system is a circular area with a central transmitter/receiver base station. BTS is raised up on a tower or top of a building. BTS has a 360-degree antenna which is tuned to create a cellular area. When a user turns a phone on, its phone number and serial number are broadcast within the F local cell. The BTS picks up the signals and informs the Switching Office that a particular device is located within its area. This information is recorded in the switching office for reference. An actual call takes place when the user enters a phone number and hits the Send button. The cellular system selects a channel G for the user to use during the duration of the call. As users travel, they may move from one cell to another, necessitating a hand off and the selection of a new channel. While in the vicinity of a cell, mobile phone users are under the control of the transmitter/ receiver in that cell. A handoff takes place when the base station

A in one cell transfers control for a user's call to a base station in another cell. When a base station begins to lose a user's signal, it notifies base stations in all the surrounding cells that the user may be moving into their cells. As the user moves into a new cell, the base station in that cell takes over the call. The frequency B of the call is changed to a frequency used in the new cell during the transition. This is because adjoining cells cannot use the same frequencies.

ix) Wireless Local Loop (WLL):

¶200

c Today, technologies provide WLL services, i.e., wireless access for home and business users to carriers and service provider network.

¶201

According to Encyclopedia of Networking & Telecommunications by Tom Sheldon, wireless local loop D ("WLL") refers to a variety of technologies for connecting subscribers to the public-switched telephone network ("PSTN") using wireless links, rather than copper wire. WLL is a practical solution for connecting subscribers in countries/areas that do not have the wired infrastructure. It is also practical in rural areas E as an alternative to laying cable. WLL is primarily a fixed wireless service (the subscriber generally stays in one place), while cellular systems offer mobile communication and roaming among different systems.

x) Basics of Wireless Communications:

¶204

¶205

Today's wireless communications would not be possible without radio signals which are generated and emitted from a sender. "They propagate through the atmosphere, and are received and interpreted by a receiver. There are two G applications for radio signals. First, they are needed for wireless communication between a mobile terminal and a fixed network, which is achieved by manipulating the parameters of the signal which process is known as modulation. Secondly, radio signals provide the basis for positior.ing, that is to say for locating the H target.

¶209

In wired network, the transmission media are copper A twisted pair, copper cable and optical fibre whereas the transmission medium for wireless communication is always the atmosphere, the space or water. Some wired systems like Ethernet make use of voltage pulses to transmit data. Signals in wireless communications are electromagnetic waves which B are analog.

¶210

¶211

Electromagnetic waves are produced and received by antennas. The receiving antenna converts radio signals from the surrounding environment into alternating current and delivers it to electronic equipment connected to the antenna, known as^c the receiver. Conversely, the transmitting antenna, on the other hand, radiates alternating current delivered by a transmitter into the surrounding environment in the form of radio or micro wave signals.

--"

--+

....

The point to be noted is that there is a dichotomy between^D receiving antenna and transmitting antenna. The antenna inside the instrument is the receiving antenna whereas the antenna on the BTS is the transmitting antenna.

¶217

In short, there exists major differences between wired and E wireless media. In wired communications, signals pass through a solid or guided medium whereas in wireless communications the technology is based on unguided media like atmosphere, space or water and, therefore, in wireless communications signals are exposed to several sources of interference on their F way from the transmitting to the receiving antenna. Broadly, we may call this process of transmission to the receiving antenna as "transmission technology" which is a part of what is called as access network in contradistinction to what is called as core network of which the numbering plan is one of the important G components. This dichotomy needs to be kept in mind for deciding the present matter. In other words, the receiving antenna in the subscriber's premises and the transmitting antenna located in the BTS are aligned and they constitute access network whereas MSC is the exchange in which there is core

¶218

¶219

[2008] 7 S.C.R.

, .

A network consisting of BSC, numbering plan, softwares etc. which are essential to identify the source from which the call originates, the movement of the subscriber from one cell to the other and the identification of the call for billing purposes. The Intelligent Network is in MSC.

¶226

¶227

Generally, radio signals are emitted from an antenna omnidirectionally and they can pass several hundreds of kilometers without being affected by obstacles (what is known as seamless), which makes radio signals very attractive for radio and television broadcast.

¶228

In wireless communications, different types of antennas are used which differ from each other in respect of directivity of signals propagation. When signals travel away from a transmitting antenna in a BTS, they are exposed to a D^{reductionintheir strength. The degree of attenuation depends} upon the distance between the transmitting antenna and the receiving antenna, the wavelength of the signals and the surrounding environment (e.g., indoor, outdoor, rural, urban etc.).

¶229

In wireless communications, the air interface (medium) E must be shared between different applications (e.g., radio, T.V., mobile, cellular systems etc.) and within a certain application between different users (radio and T.V. stations, subscribers). This is in contrast to wired infrastructures. In wireless communications, the resources of the air interface are given by F^{space, frequency, time and code and thus classified as space,} frequency, time and Code Division. The point to be noted is that all channels transmit simultaneously in the same frequency range and in the same space, thereby interfering with each other to a large extent. This means that the signals of different channels G^{are summed up during transmission and, therefore, must be} separated after reception at the receiver. One of the methods to do so is called as CDMA (Code Division Multiple Access). Under this method, different channels are separated by a code. During transmission, the signals from different senders H^{**arrivedin the form of a composed signal at the receiver.**In}

325

...

order to reconstruct the data of different senders, the receiver A has to apply the chipping sequence of the respective sender. Accordingly, the resulting signal reaches the receiver. ln the present case, "Walky'' is based on CDMA technology. So also the "Handset" of Reliance lnfocomm Ltd. is based on the same technology. It may be stressed that CDMA is the very complex B technique requiring sophisticated hardwares both in the centres and the receivers. As all senders transmit in the same frequency range simultaneously, the radiating power must be carefully aligned between them in order to guarantee that all senders can be heard at the receiver.

¶240

¶241

¶242

The fundamentals explained hereinabove are relevant to the transmissioning of data for each kind of mobile service as well as for positioning. Transmissioning of data as a concept is different from positioning. Transmissioning relies on manipulation of radio signals whereas positioning is based on D measurement of radio signals especially their travelling time or their attenuation

xi) Principles of Cellular Networks:

¶247

Mobile communications reached the market in 1980. Even at that time the major challenge was to implement advanced mobility features such as handover, roaming and localization of subscribers which required additional control channels between terminal and serving base station.

¶248

A cellular network consists of a number of radio cells where the term "cell" refers to geographic coverage area of a BTS. The size of the coverage area depends on the signal strength of the base station and the degree of attenuation. Each BTS is assigned a certain number of channels for transmitting and receiving data which is called as cell allocation ("CA"). To avoid interference between cells, it needs to be guaranteed that the neighbouring base stations are also assigned cell allocations of different channels. There are no sharp borders between neighbouring cells. Most of the time they overlap. In urban areas, a mobile device can hear a set of around 10 base stations

326

SUPREME COURT REPORTS

¶255

[2008] 7 S.C.R.

¶256

A simultaneously, and then it selects from this set of base station within the strongest signal. The number of cells a network is made up of is basically a function of the size of area to be covered and the user penetration. When building up a new network, operators first concentrate on establishing a coverage B in congested urban areas before establishing base stations in rural areas. If a network runs the risk of becoming overloaded in a certain region, the operators can increase the capacity by increasing the base stations density.

¶257

A cellular network not only consists of base stations C but also comprises a network infrastructure for interconnecting base stations, mobility support, service provisioning and connection to other networks like internet. Therefore, a cellular network consists of several access networks, which include the radio equipment o which is necessary to interconnect a terminal to the network. The access networks are interconnected by the core network. For example, in GSM, the access network is referred to as Base Station Subsystem ("BSS") whereas the core network is denoted as Mobile Switching and Management Subsystem E ("SMSS"). BSS is responsible for monitoring and controlling the air interface. BSS consists of two different components, namely Base Transceiver Station ("BTS") and Base Station Controller ("BSC"). BTS stands for "base station". It contains transmitter and receiver equipment as well as an antenna. The base station is equipped with very limited capabilities for F signalling a protocol processing. The bulk of the work, for example, allocation and release of channels is done by the BSC. The BSC is mainly responsible for control and execution of handover, a function which is needed to keep a circuitswitched connection if the subscriber moves between base G stations. Therefore, each BSC controls several base $tations, which are connected to the BSC via fixed lines or radio link systems. On the other hand, mobile Switching and Management System is a fixed network of switching nods and databases for establishing connections from and to the mobile subscriber. HLR H and VLR are two important databases which are the foundation

of the Numbering Plan in MSC. The switching components are A the Mobile Switching Centre ("MSC") and the Gateway MSC ("GMSC"). The MSC connects a number of BSCs. to the network for the purposes of localization and handover. Thus, it is the MSC which is responsible for serving a limited geographic region governed by all base stations connected to the MSC B over their BSCs. In a mobile network, when a connection is to be established it is the MSC which determines another switch depending on the current location of the mobile subscriber. Fo'r this purpose, MSC is also connected to local network for each subscriber so as to implement the numbering plan. The area c from which the call emanates, the identification of the nature of the call whether from mobile or fixed wireline is all done by the computer having the requisite software in MSC.

¶262

xii) Fixed Wireless Access WLL(F):

¶263

...

¶264

¶265

Fixed wireless access ("FWA") also known as WLL(F) has coverage between Wireless Local Area Networks ("WLANs") and cellular communication systems. The main purpose of FWA is to provide network access to buildings through exterior antennas communicating with central radio base stations. In this way, users in a building are allowed to connect to the network with conventional in-building networks.

¶266

¶267

¶268

FWA is a service in which wireless access is intended as a cheap cable replacement without additional features.

¶269

. ..,,

¶270

¶271

FWA replaces copper lines to the homes of the users by wireless links, but without the specific benefit of mobility. The original intent was to give access to customers for basic phone services bypassing the copper lines.

¶272

Fixed wireless access system is one type of service. FWA G system can also be considered as a derivative of cordless phones or wireless local area networks. FWA system essentially replaces a dedicated cable connection between the user and the public land line system. The important difference to be noted is that FWA system is not the same as cordless phones. The

¶273

¶275

...

J..

A main difference from cordless system is that in FWA system there is no mobility of the user devices. There is a difference between mobility and portability. A mobile device can be portable but every portable device is not mobile. The purpose of FWA lies in providing users with telephone and data B^{connections without having to lay cables from a central switching} office to the premises of the user. It is, therefore, cost effective as compared to wireline basic phone.

¶280

-..

¶281

¶282

xiii) Identification of a Mobile Subscriber:

¶283

In analog wireless network every mobile station ("MS") is c identified by a single number that is permanently associated with it. All connections that are established from this MS are billed to its registered owner. However, in the case of GSM, the subscriber is identified by a SIM, which is a plug-in chip card. In D^{the case of GSM, MS can only make and receive calls when} such a SIM is plugged in and active. All calls that are made from the MS are billed to the subscriber whose SIM is plugged in. Furthermore, the MS only receives calls going to the number of the SIM owner. Therefore, SIM is a fundamental importance for billing procedure. It may be noted that even in "Walky'' there is E plug-in chip card which is inbuilt in the instrument.

¶284

Mobility is an inherent feature of most wireless systems. If there is an incoming call from MS (user), the network has to know in which cell the user is located. The first requirement is F^{that a MS emits a signal at regular intervals,}^{informing nearby} base stations in the neighbourhood. Two databanks then employ this information: the Home Location Register ("HLR") and the Visitor Location Register ("VLR"). The HLR is the central data base that keeps track of the location a user is currently at; G^{the VLR is a data base associated with a certain base station} that notes all the users that are currently within the coverage area of a specific base station. If a MS moves across a cell boundary, a different base station becomes the serving base station. In other words, the MS is handed over from one BS to another. Such a handover has to be performed without

¶289

¶290

¶291

interrupting the call.

¶292

The HLR contains all the numbers of the mobile subscribers associated with one MSC and information about the location of each of these subscribers. In the event of an incoming call, the location of the desired subscriber is checked 8 in the HLR and only thereafter the call is forwarded to the location. The call is forwarded to the BSC in whose area the subscriber is routing to and selection of one BTS is the responsibility of the BSC. Therefore, one can conclude tl'lat from time to time a controlling MS (user) has to send updates of its location to its HLR. At the same time, the VLR and the MSC C contains all the information about mobile subscribers from other networks that are in the area of this MSC and are allowed to roam in the network of this MSC. The Authentication Centre verifies the identity of each MS requesting a connection.

¶293

The above discussion indicates the functionality of MSC, BSC and BTS. The data base is in MSC. It further indicates the functionality of BTS. BTS is, essentially concerned with transmission. The entire data base and the function of identifying the user and the call is in MSC. The numbering plan is one of the important elements of the network with MSC. The switching system is with MSC. The network and switching system includes the above two databases ..

¶294

¶295

The main component of network and switching ~t1bsystem ("NSS") is MSC, which controls the traffic between different F BSCs. One function of the MSC is mobility management. Other functions are paging and location update. All interactions between networks - especially the landline public switched telephone network ("PSTN") - are performed by the MSC. Therefore, the numbering pl<i"n, radio G frequency ("RF"), BTS, BSC, MSC, databases etc. form elements of the network of the service providers.

¶296

The BTSs. and BSCs. are important components of base station subsystem ("BSS"). The components of BSS are different from the components of network and switching

¶297

¶298

¶300

330

¶301

A subsystem ("NSS"). The component of NSS is MSC whereas the component of SSS consists of base transceiver stations ("STSs.") and base station controllers ("SSCs."). The STS establishes and maintains the connection to the mobile stations ("MSs.") within its cell. The interface between the MS and the s STS is the air interface. The STS hosts the antennas and the radio frequency hardware of a base station, as well as the software for multiple access. Several BTSs. are connected to. one BSC; they are either co-located, or connected via landline, microwave radio links, or similar connections.

¶302

C The SSC has a control functionality. It is responsible for Hand Over ("HO") between two STSs that are connected to the same SSC. Distribution of the functionalities between STS and SSC may differ depending on the manufacturer. In most cases, one SSC is connected to several STSs. Therefore, it is possible 0 to increase the efficiency of implementation by shifting as much functionality as possible to the SSC. In general, the SSS is responsible for channel assigning, maintenance of link quality and HO, power control, coding and encryption.

¶303

xiv) Difference between Wireless Systems and E Services:

¶304

In systems, mobility per se is of value - e.g., in cellular telephony. Such services can charge a premium to the customer - i.e., it is more expensive than equivalent wired systems. In F cellular telephony the per-minute price is higher than landline telephony and yet on account of competition, the price has come down.

¶305

Services where wireless access is intended as a cheap cable replacement without additional features have to be costG effective, as the infrastructure thereof has to be cheaper than wired connections. The classic example of such services is FWA.

¶306

In the case of systems, mobility is of value whereas in case of services, wireless access is a cheap cable replacement without additional features.

¶375

(b) Principles of Wireless Access:

¶376

Principles of wireless access have also been enumerated in recommendations of International Telecommunication UnionE Radio Communication Assembly ("ITU-RCA"). They are as follows:

¶377

"1 Introduction

¶378

This Recommendation consists primarily of those terms F and definitions that are considered essential to the understanding and application of the principles of wireless access. However, they are not exclusive to wireless access and are recommended also for application, insofar as they are relevant, to other types of telecommunication G systems and services.

¶379

Included are terms that may already be defined in the Radio Regulations (RR) and other ITU-R/ITU-T Recommendations. However, the definitions given here embrace only the essential concepts a;id on this basis it H is considered that they are not inconsistent with the more

¶380

TATA TELESERVICES LTD. v. BHARAT SANCHAR 335 NIGAM LTD. AND ORS. [KAPADIA, J.]

¶381

specialized definitions that appear in those texts.

¶382

¶383

Where a truncated term is widely used in an understood context, the complete term is quoted following the colloquial form.

¶384

Some definitions include terms in italic face to indicate that these terms are defined elsewhere in this Recommendation.

¶385

Technologies in use today for implementing wireless access include cellular systems, cordless phone and cordless telecommunication systems, satellite systems, etc. New technologies and systems such as IMT-2000, wireless broadband ISDN, wireless ATM, HAPS, etc., also form part of wireless access if they satisfy the basic criteria of end-user radio connection(s) to core networks

¶386

Wireless access may be considered from many perspectives, for example:

¶387

Mobility capabilities of the terminal: fixed, nomadic (may be used in different places but the terminal 1T1USt be stationary while in use), mobile, restricted mobility (e.g. within a single cell), etc.

Service support capabilities: narrow-band, broadband, multimedia, etc.

¶393

Type of telecommunication service: conversational, distribution, information retrieval.

¶394

¶395

Connectivity: (which would depend on the switched network that the terminal accesses,

¶396

e.g. Internet, PSTN, etc.).

¶397

¶398

Radio transmission technology: access technique

¶399

(TOMA, CDMA, etc.), modulation

¶400

technique (analogue, digital, etc.), duplex technique (FDD, TDD, etc.), etc.

¶401

¶402

336 SUPREME COURT REPORTS

¶403

[2008] 7 S.C.R.

¶404

¶405

Delivery mechanism: terrestrial, satellite, etc.

¶406

Of particular interest are the mobility characteristics of wireless access systems; thus this Recommendation provides definitions of the terms "fixed", "mobile" and "nomadic" wireless access.

¶407

¶408

The purpose of this Recommendation is to specify terms and definitions for terrestrial wireless access.

¶409

2 Scope

¶410

¶411

The Recommendation specifies definitions for terms primarily focused in the field of terrestrial wireless access systems. Wireless access applications may be provided within the definitions of the radio services FS, MS, FSS and MSS contained in the RR.

¶412

¶413

¶414

The ITU has deprecated the use of the term "loop" (see References below: CCITT Blue Book, Vol. I, Fascicle 1.3, 1988); for this reason, and more so because this term does not make any sense with radio technologies, the use of the terms that include loop are deprecated. These include wireless local loop, radio local loop, and wireless access local loop.

¶415

¶416

It should be noted that in many cases systems may be able to support a mixture of users (i.e. fixed, mobile and nomadic) and possibly with restrictions on the type of mobility It is not practical to define terms for each possible combination, but those above should suffice to refer to the primary characteristics of the system."

¶417

In addition, the said recommendation also defines relevant G terms. The said definitions are contained in clause 4.1, which reads as follows:

¶467

The said UAS licence covers "access service" which includes wireline and/or wireless service including full mobility, limited mobility and FWA. Basically, in these civil appeals we are concerned with three wireless services, namely, full mobility, limited mobility and FWA. What is FWA has also been explained earlier in this judgment. We quote hereinbelow clause 2.2(a) and clause 2.2(c)(i), which read as follows:

¶468

¶469

¶470

"2.2 (a) The SERVICES cover collection, carriage, transmission and delivery of voice and/or non-voice MESSAGES over LICENSEE's network in the designated SERVICE AREA and includes provision of all types of D access services. In addition to this, except those services listed in para 2.2 (b)(i) licensee cannot provide any service I services which require a separate licence. The access service includes but not limited to wireline and I or wireless service including full mobility, limited mobility as defined in clause 2.2 (c) (i) and fixed wireless access. However, E the licensee shall be free to enter an agreement with other service provider(s) in India or abroad for providing roaming facility to its subscriber under full mobility service unless advised I directed by Licensor otherwise. The LICENSEE may offer "Home Zone Tariff Scheme (s)" as a subset of F full mobile service in well defined geographical Areas through a tariff of its choice within the scope of orders of TRAI on the subject. Numbering and interconnection for this service shall be same as that of Full mobile subscribers. G

¶471

2.2 (c) (i) In respect of subscriber availing limited mobility facility, the mobility shall be restricted to the local area i.e. Short Distance Charging Area (SDCA) in which the H

subscriber is registered. While deploying such systems, the LICENSEE has to follow the SDCA based linked numbering plan in accordance with the National Numbering Plan of the respective SDCA within which the service is provided and it should not be possible to authenticate and work with the subscriber terminal equipment in SDCAs other than the one in which it is registered. Terminal of such subscriber in wireless access system can be registered in only one SDCA. Multiple registration or Temporary subscriber/ Subscription facilities in more than one SDCA using the same Subscriber terminal in wireless access systems is not permitted and the same Subscriber Terminal cannot be used to avail Limited Mobile facility in more than one SDCA. The system shall also be so engineered to ensure that handover of subscriber does not take place from one SDCA to another SDCA under any circumstances, including handover of the calls through call forwarding beyond SDCA. The Licensee must ensure that the mobility in case of such limited mobile service/ facility remains restricted to SDCA."

¶479

¶480

¶481

The concept of limited mobility has been defined in clause 2.2(c)(i). The UAS Licence clarifies vide clause 2.2(c)(ii) that the Basic Service operators like the appellants after migration to Unified Access Licence Regime can also offer limited mobility service for such customers who so desire.

¶482

In these civil appeals we are concerned with the concept of limited mobility as a service which attracts ADC.

¶483

Clause 2.2(d)(i) inter alia provides for compliance with standards prescribed by !TU-RCA which have been quoted G hereinabove. We quotre hereinbelow clause 2.2(d)(i), which reads as follows:

Meaning of Interconnection Usage Charges ("IUC")/ ADC:

¶489

¶490

On 29.10.2003, TRAI notified IUC. ADC is a part of IUC. ADC is a percentage of the revenue. The framework of IUC regime was established by TRAI through its Regulation dated 24.1.2003 which was subsequently reviewed on 29.10.2003 and 6.1.2005. IUC has to be determined based on c minutes of usage for various network elements and the cost of these elements.

¶491

¶492

ADC, on the other hand, is based on the consideration of cost based rent, local call charges, low rental in rural areas, free calls etc. to make the basic telecom services affordable to D the common man, to promote universal service and universal access as required by NTP, 1999. It is important to note that ADC does not arise out of any legal right. It arises out of TRAl's consideration of smoothening the transition process during competition, i.e., providing support during E transition period when costs of access is not fully recoverable from the revenues from access line monthly rental under the existing tariff regime due to competition in the market. In other words, ADC is a depleting regime for ADC purpose. Calls to/ from WLL(F) is similar to calls to/ from fixed lines. It is F important to note that fixed wireless services, provided by fixed service providers, and unified access service licences are classified as Fixed Services. However, fixed wireless services for all purposes tantamounts to full cellular services and can be offered seamlessly throughout the G SDCA which created a non level playing field for cellular. operators vis-a-vis the fixed wireless service providers, which has led to the present dispute, which is primarily concerned with the "range of mobility" of Fixed Wireless Terminals provided by appellants herein and Reliance lnfocomm and not with the size H

Submissions:

¶499

B 12. Mr. Arun Jaitley, learned senior counsel for the appellants, submits that the question to be decided in this case is whether the appellants' instrument ("Walky'') falls in the category of Fixed Wireless Service or WLL(M) service. According to the learned counsel, the question of classification c^{under TelecomRegulatory Authority of India Act,1997 ("1997} Act") can only be decided upon by TRAI and not by BSNL as is purported to have been done in the present case, particularly when BSNL is a competing service provider and a contracting party under IUC Regulations. In this case, BSNL has demanded D^{ADC from the appellants for the period 14.11.2004 to 26.8.2005.} Learned counsel urged that, according to the appellants, the instrument "Walky'' is a fixed wireless phone having portability as its feature. That, BSNL had no authority to classify the said instrument as a mobile phone.

¶500

E 13. According to the learned counsel, the abovementioned WLL(M) is a service. It refers to a mobile set and not to a portable FWP and, therefore, the said instrument "Walky'' which is portable is not classifiable as WLL(M). That, in any event, classification disputes lay before TRAI under the 1997 Act and that BSNL F^{has no authority to classify/reclassify the said "Walky" as WLL(M).} In this connection, it is urged that BSNL could have filed its complaint before TRAI and BSNL could not have unilaterally called upon the appellants to pay ADC after such reclassification. The questions raised on behalf of the appellants G^{is:Who pays ADC? Who decidesastowhopays?Inthis} connection, it is further submitted that under section 11 (b)(ii) of the 1997 Act, the terms and conditions for grant of Interconnectivity is to be fixed by TRAI; it is mandatory function of TRAI to do so and, therefore, it 1s beyond the competence of H^{BSNL to re-classify and fix the ADCliability on to the appellants.}

¶506

Learned counsel urged that fr0rn 1997 to 2004, the A said "Walky'' had been in the market to the knowledge of BSNL; the market knew the distinction between the three services and that the said Instrument stood classified during above period as WLL(F). That, GOTIT had also treated it as WLL(F). That, the appellants had moved TDSAT, in the present case, to set B aside the demand of BSNL.only on ground that BSNL had no authority to re-classify the said instrument from Fixed to WLL(M) service. That, BSNL could have challenged the use of "Walky'' without payment of ADC before the TRAI in which event the said Authority could have taken up and decided the cla,;sification c dispute, but was not done.

'"'

•

It is next urged that "Walky" as an Instrument is portable, not mobile and, therefore, BSNL had erred in reclassifying Walky as WLL(M). Challenging the impugned decision of TDSAT, it is urged· on behalf of the appellants that TDSAT had erred in D equating portability with mobility. That, the said two conGepts are different. That, the Telecommunication Interconnection Usage Charges Regulations, 2003 ("2003 Regulations") tre.1ted WLL(M) and WLL(F) as a separate class of service. That, in the absence of any change in the technology or the instrument E and merely because of the advertisement issued by the appellants, the character of service or its classification cannot change. In this connection it may be noted that appellants had given on Advertisement (Ex.-P8) in which it was stated that "Walky'' combines the best features of Mobile Phone and the F Landline. That, BSNL had complained to TRAI regarding the advertisement in which "Walky" was shown as WLL(F) by invoking Rule 6 of the 2003 Regulations and when the matter was sub-judice before the Authority, BSNL raised the unilateral demand for ADC on the appellants which was mis-conceived. G That, under the contract between BSNL and the appellants, there was no provision to dis-connect the Access Facility, unilaterally.

¶511

Learned counsel urged that in the dispute raised by the appellants before TDSAT the only question raised was regarding unilateralism on the part of BSNL which TDSAT

¶512

¶513

344 SUPREME COURT REPORTS

[2008] 7 S.C.R.

,,, .

A failed to decide and, therefore, the matter needs to be remitted to TRAI. In this connection it is urged that under clause 2. 7 of the Consultancy 'Paper the "extent of portability" was the question pending to be decided by the Authority and pending decision, BSNL had no authority to raise the demand.

¶518

On Technology, learned counsel urged that after introducing the concept of ADC, the categories of the services were Fixed Wireline, WLL(F), WLL(M) and Cellular which is now re-classified unilaterally by BSNL and DoT as Fixed Wireline; WLL(F) = WLL(M) and Cellular. Learned counsel urged that if C WLL(F) had to be shifted to WLL(M), then that question needs to be looked into by the Authority, hence remand becomes necessary as such re-classification cannot be done by BSNL unilaterally. Learned counsel submits that correct classification for ADC could have been done only by TRAI and not by BSNL/ D DoT and that too after following the procedure under section 11 of the 1997 Act.

¶519

Learned counsel next urged that neither in the Licence nor in the 2003 Regulations is there any Premises Specific Restriction ever imposed and, therefore, it was not open to E BSNL to make the impugned demand as the said restriction was not there during the relevant period. In this connection it was urged that during the entire period between 1997 to November, 2004, even DoT understood "Walky'' to be portable in the entire SDCA; that only in March, 2005 it gave F directions to the contrary to the appellants incorporating the above "Premises Specific Restriction" and that too without any change in the licence or the IUC Regulations 2003; that till 4.3.2005 the said restriction was never mentioned; that without complying with section 11 of 1997 Act, TRAI could not have G issued such a directive on 4.3.2005, particularly when it seeks to impose a liability to pay ADC with retrospective effect. Learned counsel submits that, in the circumstances, matter of classification/reclassification arises which needs to be decided byTRAI.

"-·

-J

Mr. Gopal Subranianium, learned senior counsel on behalf of respondent no. 1 - BSNL, at the outset submits that, this civil appeal is infructuous. In this connection, it is urge_d that by Circular dated 4.3.2005 issued byTRAI, all Access Providers (including appellants herein) were di~ected to ensure that the terminal used for Fixed Wireless Services should be confined to the premises of the subscriber as the issue of mobility had revenue implications. Learned counsel submits that this circular has not been challenged till date and, therefore, this civil appeal is infructuous.

¶526

¶527

It is next urged that the contention of.the appellants^c that when consultation process was on BSNL could not have made the Demand has no merit because in that Process' the question was not of reclassification but the question w~s whether ADC was payable to other Fixed Service Providers, besi.des BSNL. In this connection, it was pointed out that before 1.2.2005, D appellants herein used to receive ADC as Fixed Service Provider in respect of "Walky'', however, after that date BSNL alone became entitled to ADC which led to di?putes. It is urged that neither the Consultation Paper nor the 2003 _ ~egufations was concerned with characteristics of WLL(M) services as that E issue stood decided by TRAI vide circular dated 4:3.2005 as well as by Order dated 26.8.2005 issued by DoT by which it was held that appellant had provided Fixed Wireless Terminals as Mobile Terminals. The said Order of DoT stood complied with by the appellant and, therefore, there was no merit in the F contention of the appellant on the issue of unilateralism. The said Order dated 26.8.2005 was passed by DoT after giving show cause notice. It is based on breach of licence conditions by appellants.

¶528

¶529

On the technology, it is urged on behalf of BSNL, that G WLL(M) is a service which is put in the "Walky''. It is urged that WLL(M) is a service given by the instrument "Walky''. What is relevant is the Service and not the Instrument. It is urged that the appellants herein had invoked the Original Jurisdiction ofTDSA( on the question of characterization of service which has been H

.- ',

A answered in favour of BSNL. It is urged, that nature and classification of instrument was not relevant; that what was relevant was the feature of the service in the instrument "Walky'' and whether that feature made it WLL(M) service, to which ADC stood attracted. All these questions have been answered by B^{TDSAT by its impugned judgmentinfavour of BSNL. By the} impugned judgment, it has been held by TDSAT that Walky Calls attract ADC under the Regulatory Regime.

¶535

It was next urged that on facts there was no unilateralism as the Demand was made by BSNL only after the TRAI and the c DoT had issued the above Circular and Directive respectively which have not been challenged. It is pointed out that in fact appellants have complied with Do T's order. Learned counsel would submit that ifthere was compliance of the Order/Directive of DoT dated 26.8.2005 there is no reason why appellants D should not pay ADC for the period in question, viz, 14.11.2004 to 26.8.2005. According to learned counsel, compliance of DoT's Order dated 26.8.2005 itself indicates that even according to the appellants. ADC was payable in respect of the service, i.e., WLL(M) and, therefore, there is no merit in the E^{argument advanced on behalf of the appellants that ADC could} not be charged without change in the conditions of licence or 2003 Regulations.

¶536

¶537

It was next contended that under 2003 Regulations, reference is made to Fixed Wireless Access, Mobile Wireless F Access and Nomadic Wireless Access. Before TDSAT, the controversy was regarding WLL(M) Service in SDCA. Before us it was contended that the levy of ADC is not on movement of Walky within SDCA but it is in respect of service rendered in SDCA. That, WLL(M) is a type of service within G SDCA.

¶538

Learned counsel would submit that with the introduction of Unified Access Service Licence ("UASL") in 2003 the distinction between Fixed Wireless, WLL(M} and mobile stood H obliterated. The said UASL 2003 brought in the Numbering Plan

¶540

¶541

¶542

¶543

which categorized the series in the said Plan to identify and measure the call for billing purposes. That, in terms of clause 2 of UASL, "mobility" refers to service(s) within SDCA.

¶544

¶545

The above arguments of learned counsel for BSNL were adopted by Dr. A.M. Singhvi, learned senior counsel for Cable Operators Association.

¶546

¶547

Mr. Rakesh Dwivedi, learned senior counsel appearing for intervenor-TRAI would submit that in November, 2000, TRAI recommended Limited Mobility Service, i.e., WLL(M) on 25.1.2001, DoT permitted it, whereas Walky came into the c market only in October, 2004. According to learned counsel, vide IUC Regulations, 2001, WLL(M) was defined which was incorporated in UASL on 26.11.2003 and, therefore, appellants were fully aware of the difference in WLL(M) Service vis-a-vis WLL(F) and Cellular.

¶548

¶549

..,

¶550

On technology, learned counsel submits that under WLL(M), the terminal of the subscriber must be fixed to a socket in the subscriber's premises. That, service given by the appellant is that of Limited Mobility. That in case of WLL(F) the Basic Phone Instrument has to be fixed indoor and since that is not the case of appellants, the instrument "Walky'' would fall in the category of WLL(M) .

Finding:

,.- .

India's phenomenal growth in the mobile subscriber F base and penetration rate (or teledensity as measured by number of phones per hundred) has attracted global attention. Mobile phones have introduced competition in providing access and ~ervices at global competitive prices and state-of-art technology. The competition is now relevant not only among the G private providers of mobile services, but also among the private and public providers of both fixed and mobile services. India's NTP 1999 emphasised the Government's commitment to provide basic telecom services to all people at affordable and reasonable prices. This commitment is called the Universal H

¶558

A Service Obligation ("USO").

¶559

At the outset, it may be stated, that, Regulatory Restriction should not be confused with technology limitation. With the technological advancement, "extent of mobility" has gone way beyond the "Premises Specific Restriction" but in this B case we are not concerned with technology but with the levy of ADC. According to some authors, ADC is a tax. In the Revenue Regime, the Authority imposing the levy is not always bound by the concepts in technology. It is open to the Authority under the Revenue Regime to impose by way of Regulatory Restriction a c parameter like Premises Specific Restriction to explain the concept of Limited Mobility.

¶560

WLL is a technology. In this case we are only concerned with Wireless Local Loop Mobile Service. As a D^{technological concept, wireless inlocal loop technology simply} means that the subscriber is connected to the nearest exchange of the appellants (MSC) through BTS (which is only concerned with transmission) through a radio link instead of through the copper wires. In general, it is cheaper than copper wire connectivity. In traditional wire-line network, the cost of the Last E Mile amounts to substantial portion of the total cost of putting up the network. CDMA and FDMA are technologies used for WLL.

¶561

In this civil appeal we are not concerned with WLL per se but with the concept of "limited mobility".

¶562

¶563

WLL is also called Broadband Wireless Access (BWA) or fixed-radio access or fixed-wireless access or fixed wireless terminal (FWT).

¶564

FWT units differ from mobile terminal units operating G^{within cellular networks -such as GSM - in that a}^{fixedwireless} terminal or deskphone will be limited to an almost permanent location with no roaming facility.

¶565

WLL + FWT are generic terms for radio based telecommunications technologies and the respective devices H which can be implemented using a number of different wireless

¶570

and radio technologies. In generic sense, WLL is a technology. It cannot be equated to WLL(M) which is a service like WLL(F). Under the Worldwide Database, WLL does not refer to Limited Mobility. Worldover WLL is used to provide Fixed Wireless Access for speedy roll-out of fixed services. However, under the NTP 1999, cellular operators are allowed to offer all types of mobile services whereas fixed operators like the appellants are allowed to offer fixed services.

¶571

¶572

¶573

The core issue, therefore, is not whether Limited Mobility is or is not possible but whether fixed operators are liable to pay ADC when the service(s) provided by them fall in^c WLL(M) service.

¶574

r·

¶575

The main contention advanced on behalf of the appellants is regarding alleged unilateralism by BSNL in calling upon the appellants herein to pay ADC. According to the D appellants, BSNL is a service provider and a competitor to the appellants, therefore, BSNL has no authority to impose ADC liability on the appellants. According to the appellants, BSNL is a contracting party and, therefore, BSNL has no authority to levy ADC unilaterally on the appellants. According to the appellants, E TRAI had issued its directive dated 4.3.2005 at the behest of BSNL without TRAI itself decided the categorization of service. According to the appellants, in any event, TRAI had acted at the behest of BSNL in issuing the said directive. According to the appellants, the said directive seeks to treat the Walky calls as F WLL(M) whereas all over the years between 1997 to 2004 the said service stood classified as WLL(F). According to the appellants, if at all TRAI wanted to reclassify the said service as WLL(M) it ought to have followed the procedure laid down under Section 11 of the 1997 Act. The effect of such directive, according to the appellants, is not only to reclassify the services^G but it also seeks to amend the terms and conditions of UAS Licence. It may be stated that directive dated 4.3.2005 stood clarified by DoT vide two clarifications dated 23.3.2005 and 26.8.2005. According to the appellants, the said clarifications were issued in the context of advertisement given by the H

¶576

¶577

350 SUPREME COURT REPORTS

¶578

[2008] 7 S.C.R.

¶579

A appellants, which were later on withdrawn and that the said directive had no connection with ADC chargeability. According to the appellants, Do Tis a licensor. According to the appellants, DoT had no authority to categorize Walky as WLL(M). According to the appellants, during the period 1997 to 2004, Do T and TRAI B have treated Walky as WLL(F). According to the appellants, by reclassifying Walky as WLL(M), DoT had sought to unilaterally reclassify Walky as WLL(M) which amounts to change in licence conditions. According to the appellants, reclassification could have been done only by TRAI under Section 11 of 1997 Act and C not by DoT. Therefore, as can be seen from the above arguments, it is clear that the basic complaint of the appellants is based on unilateralism in imposing ADC liability on them.

¶580

Before proceeding to deal with the arguments on unilateralism, we quote hereinbelow, in extenso, the directive D issued by TRAI dated 4.3.2005, clarification issued by DoT dated 23.3.2005 and further clarification issued by DoT dated 26.8.2005, which read as follows:

¶585

The Authority has noted that fixed wireless services were F being provided through fixed wireless terminals in which the location of the network access point was fixed and end user terminal was connected to it. Recently it has come to the notice of the Authority that new terminals being deployed by access providers do not have any fixed G network Access Point physically located at the address of the subscriber. In this regard certain complaints including those of misleading advertisements have also been received by the Authority and subsequently show cause notices were issued to the concerned operators. The H responses given by the service providers were not found

to be in order.

As the issue of mobility has implications with respect to applicability of ADC, the Authority directs you to strictly ensure that the terminal used for fixed wireless services should be strictly confined to the premises of the subscriber. All Access B Providers should also ensure that there are no misleading advertisements in the electronic and print media. It should also be further noted that it is licensee's responsibility to ensure that the subscriber terminal is operated in accordance with the terms of the License for fixed lines.

Further it was pointed out that BSNL is being severely disadvantaged as they have not received ADC from WALKY Calls.

¶640

Whereas M/s. Tata Teleservices Ltd. was supposed to provide services within the scope of its licence agreement B and it was expected that by way of advertisement or promotion of its services, the subscriber should not be misled.

¶641

Whereas a notice was issued for alleged violation of conditions and not limited to clause 2 of Unified Access c Services Licences on 06.01.2005 and 31.01.2005 regarding WALKY service.

And whereas M/s Tata Teleservices Ltd. replied to the notice vide letter dated 21.01.2005 and 02.02.2005 of stating that there has been neither any attempt nor any intention to mislead any subscriber in relation to services being provided by M/s TTSL and they continue to provide services within this scope of licences. The Fixed Wireless Terminal (FWT) instruments are prominently advertised as bulky desktop phones and therefore customer is clearly informed of the nature of the services and the phone instrument. The numbering scheme of both FWT & Wireline Phones is same and is different from that of limited mobile services. The FWTs covered by one or sometime more than one Base Trans-receive Stations (BTSs).

¶647

M/s TTSL further submitted that "Walky'' is a brand established by Tata Teleservices essentially to promote and market their desktop Fixed Wireless Phones. These Fixed Wireless Phones combined the advantages of both mobile phones and landline phones.

¶648

Further, clarification regarding Fixed Wireless Terminals was issued vide this office letter No. 10-10/03-BS-llNol.VI dated 23.03.2005 vide which it was clarified that the Terminal used for Fixed Wireless Services should be strictly

confined to the premises of the subscriber where the telephone connection is registered. Separate levels within allocated SDCA based link numbering scheme are to be used forWireline and Fixed Wireless Services. Wherever such restriction cannot be imposed, it shall be treated as WLL (M) feature for all purposes.

¶653

¶654

¶655

It is needless to mention that the word "Fixed" is clearly understood and it does not require a separate definition in legal or common parlance.

¶656

M/s TTSL submitted compliance to letter dated 23.03.2005 c vide its replies dated 31.03.2005 stating that, "the Licensor would surely be aware of the inherent "Soft handover" nature of CDMA technology due to which CDMA terminals (FW or mobile) utilize network and proving to be extremely spectrally efficient Therefore, the implementation of any D restriction would require considerable changes to the network, which need time, effort and considerable resources to complete something that DoT requires to provide. Nevertheless, under constraints of time, some actions have been initiated which are detailed further in E this letter". Further vide letter dated 08.04.2005, Mis TTSL has stated that they have taken some exercise to restrict service to the BTSs.

After examining all the responses of Mis Tata Teleservices Ltd. on the above mentioned subject, it is noticed that F initially, M/s Tata Teleservices Ltd. has not taken appropriate steps to restrict the mobility within the premises and has advertised such service where consumer can have the impression that mobility 1s one of the features. In the response also M/s TTSL stated that G fixed wireless phones combine the advantage of both mobile and landhne phones. Moreover, the measures taken, later on, to restrict the mobility has also been found to be unsatisfactory. It is. therefore, clearly established that mobility is not restricted to the premises and the

Analysing the directive dated 4.3.2005 issued by TRAI, the point which arises for determination is whether such directive is clarificatory or amendatory. According to TRAI, it is clarificatory F whereas according to the appellants it is amendatory. In this case, as stated above, we are concerned with the demand of ADC on the appellants for the period 14.11.2004 to 26.8.2005. According to the appellants, such a directive dated 4.3.2005 cannot operate retrospectively. This is the key issue which we G need to decide. In this connection, it may be noted that the said directive was issued to all access providers. The said directive came to be issued as it was brought to the notice of TRAI that new terminals were being deployed by access providers which terminals do not have any fixed network access point physically H located at the address of the subscriber. In the said circular dated

¶679

4.3.2005, TRAI noted that fixed wireless services were required A to be provided through fixed wireless terminals with the location of the network access point being fixed and with the end-user terminal being connected to it. That, it had been brought to the notice of TRAI that new terminals were being deployed by certain access providers which did not possess fixed network access B point physically located in the premises of the subscriber (PSR). Therefore, by the said circular, TRAI directed the service providers to strictly ensure that the terminal used for fixed wireless services should strictly comply with premises specification restriction, i.e., to the premises of the subscriber. c This stipulation in the directive, according to the appellants, constitutes a new requirement which has the effect of amending the terms and conditions of the UAS licence as well as the Telecommunication Interconnection Usage Charges Regulation 2003. The said directive dated 4.3.2005 stood followed by D letters from DoT dated 23.3.2005 and 26.8.2005 .

¶680

...

¶681

In our view, there is no merit in the above contention advanced on behalf of the appellants that the above directive dated 4.3.2005 is amendatory and not clarificatory. The reasons are as follows.

¶682

~ '

¶683

,..

¶684

Firstly, the UAS licence classifies wireless service into three categories, namely full mobility, limited mobility and fixed wireless access. As stated above, in FWA there is no mobility of the User Device. FWA replaces copper lines to the homes of the users by wireless links but without the benefit of mobility for^F the User Devices. FWA is one type of service. Mobility is a service feature. In FWA system, the location of end-user terminal and the network access point to be connected to end-user are fixed. In circular dated 4.3.2005, TRAI has used certain technological terms generally used in telecommunications like G network access point, end-user terminal and fixed network access point. These terms find place in the generic requirement formulated as far back as 1996. They also find place in the Principles of Wireless Access formulated by ITU-RCA. Keeping in mind the definitions given both in the technical references as H

¶689

A well as in the principles of wireless access formulated by ITURCA. it is clear that Premises Specific Restriction ("PSR") is not something new which stood evolved for the first time by circular dated 4.3.2005. In substance, PSR emanates from concepts, which are well known in telecommunications, both in B technological references as well as in terms of generic requirements and in terms of principles of wireless access. We may state that broadly FWA is called WLL(F). As stated above, the UAS Licence refers to three types of wireless services, namely, full mobility, limited mobility and FWA. As stated, in C FWA. the location of the end-user (Walky) and the network access point (antenna connected to the end-user) are both fixed whereas in the case of mobile wireless access, the location of the end-user is mobile. WLL(M) is a hybrid between FWA and MWA. Wireless access may be considered from many perspectives. In this case, we are concerned with mobility 0 capabilities of the terminal: fixed, nomadic, mobile, restricted mobility etc. As stated hereinabove, the main purpose of FWA [WLL(F))] is to provide network access to buildings through exterior antennas communicating with Central Radio Base Stations. In FWA. users in a building are allowed to connect to E the network with conventional in-built networks. FWA is a serJice. It is intended as a cheap cable replacement, without additional features. Wireless systems differ depending upon the amount of mobility that they allow for the users. FWA system is a derivative of cordless phones. In FWA there is no mobility of the F user devices. This is where the concept/principle of PSR emerges. As stated above, there is a difference between mobility and portability. A terminal may be portable but every portable device is not mobile. Therefore, in our view, the concnpts mentioned in circular dated 4.3.2005 issued by TRAI G exist in telecommunications right from 2001. The said circular merely clarifies and brings out the concept premises specific restriction.

¶690

To sum up, in WLL(F) the telephone is the access point if the antenna is in-built in the telephone. If the impugned

...

service is operable throughout SOCA it is WLL(M). In WLL(F), location of end-user termination and the network access point to be connected to the end-user are fixed. If the impugned service cannot comply with PSR it is classifiable as WLL(M) for IUC. AOC, Numbering Plan etc. Lastly, the only difference between fixed wireline and WLL(F) is that WLL(F) is a cheap cable replacement wit~out additional features. WLL(F) is limited to specific premises of the subscriber or permanent location.

¶702

¶703

¶704

Secondly, the facts noted above indicate that the classification of wireless service is done under the licence and^c based on that classification, chargeability for imposition of interconnection usage charges and AOC is contemplated by IUC Regulation of 2003. In other words, classification is done by UAS licence followed by chargeability under !UC Regulation, 2003. Therefore, it would be wrong to say that vide circular dated D 4.3.2005 Walky has been reclassified as WLL(M) for the first time by TRAI. If the concept of FWA embodies PSR and that too from 2003 then it is clear that the said circular dated 4.3.2005 is clarificatory. It does not alter the terms and conditions of the licence. As stated, FWA is one of the wireless services E contemplated by UAS Licence which is dated July, 2003, therefore, much prior to circular dated 4.3.2005 these concepts were known to all access providers right from 2003. Therefore, the said circular cannot be called as amendatory. It is purely clarificatory in nature. F

¶705

Thirdly, as stated above, in this case we are concerned with regulatory regime. ADC is a levy. Its levy depends on mobility as a service feature. As stated above, the numbering plan, radio frequency etc. are all importantelements of a network. The numbering levels for fixed wireless services and for WLL(M) G services are different. So also the numbering levels for fixed wireless service, limited mobility service and full mobility service are different. The identification of the call whether originating from mobile or from Walky or FWA has a correlation with the numbering plan which is an important element of the network of H

A the appellant in its MSC. For levy of ADC, integrity of numbering plan is very important. In the present case, TRAI has detected that the appellant is providing WLL(M) service in the garb of fixed wireless phone service (FWA) which disturbs the integrity of the numbering plan. It is important to note that in the case of B^{full mobility, the rateisdifferent as compared to the rateinthe} case of limited mobility as compared to the rate in fixed wireless service. This difference in the rates is spelt out in IUC Regulation, 2003. It is for this reason that even in the clarification issued by DoT on 23.3.2005 that DoT had warned the access providers c^{by pointing out that the issueof mobility has implication with} respect to the applicability of ADC. It was further clarified that if it is not possible for the access provider to comply with the requirement of PSR then the Walky services shall be treated as WLL(M) service for all purposes including numbering plan, D^{interconnection usage charges, ADC etc. This is because a} separate level with allocated short distance charging area based link numbering is to be used for wireline and fixed wireless services. ADC is a levy. It is based on what is called as recognition of services. Mobility is an important service feature. The record indicates that right from 2003 when UAS licence E stood issued the classification was contemplated by the licensor-DoT when it categorized wireless service into full mobility, limited mobility and FWA. ADC, interconnection usage charges etc. follow that classification. IUC Regulation, 2003 imposes the statutory charges based on the classification in F the licence. What is important in this case is that besides technological data, even as a matter of policy if there is a contract between DoT and the access provider in terms of UAS licence which provides for three categories then the levy of ADC would depend upon the service which is rendered to the user by the G access provider. In the circumstances, apart from technology, this case is more on tax policy which levies ADC on services which fall in the category of WLL(M).

¶711

Fourthly, wireless systems differ in the amount of mobility that they have to allow for the users. The ability to move

around while communicating is one of the main features of A wireless communication for the user. However, within that requirement of mobility, different grades exist:

¶719

(i) Fixed Devices:

¶720

¶721

¶722

Fixed devices are placed only once. There is no B mobility of the user devices in this grade. The main object for using such devices lies in avoiding the laying of cables. All wired communications fall also in this category (example: PSTN).

¶723

¶724

(ii) Nomadic Devices:

¶725

Nomadic devices are placed at a certain location for a limited duration of time and then moved to a different location. Laptops are typical example of nomadic devices.

¶726

¶727

(iii) Low Mobility:

¶728

Cordless phones are typical example of low mobility.

¶729

~ ~-- .... -

¶730

The point to be noted is that in the licence we have three types of wirelss services, namely, limited mobility, full E mobility and FWA. IUC levies the charge based on this classification. ADC is a part of IUC. ADC is also levied under IUC Regulation, 2003. In the case ofWalky, the instrument can be put in the car, it can be carried throughout SDCA and Walky calls can originate not only from the subscriber's premises but F it can also originate from any point in the SDCA. Because of this mobility, it is classifiable in the category of limited mobility. As stated above, in the case of FWA [WLL(F)] there is no mobility of the user device. When there is no such mobility of the user device, it is similar to all wired communications. Therefore, FWA is categorized as WLL(F). All wired communications can also^G fall in WLL(F) for the purposes of levy of ADC. However, since the user device in the case in hand is mobile throughout SDCA, the services which the instrument Walky offers has to be categorized as WLL(M) service. In the present case, we find

¶731

¶732

SUPREME COURT REPORTS

,._

A merit in the contention advanced on behalf of BSNL that the appellants were providing WLL(M) services during the above period in the garb of FWA or fixed wireless phone services and thereby they have infringed the integrity of the numbering plan. Therefore, ADC is payable by the appellants for the aforesaid B^{period, namely, 14.11.2004 to 26.8.2005.}

¶738

Lastly, as stated above, classification of services stood effected under UAS Licence 2003. Under the terms and conditions of that licence, the access providers were required to maintain the integrity of the numbering plan. This was one of c the conditions of the licence. Similarly, classification/ categorization of wireless services was done under the licence. The categorization constituted the term of the licence. As a matter of follow-up for the purposes of levy of certain charges, including AOC, !UC Regulation 2003 stood enacted. Under Section D 11(1)(b) of the 1997 Act, the TRAI is empowered to ensure compliance of terms and conditions of licence and to fix the terms and conditions of inter-connectivity between the service providers [see: section 11 (1 )(b)(i) and (ii)] Similarly, under Section 11(1)(c), TRAI is also authorized to levy fees and other E^{charges at such rates andinrespect of such services asmay} be determined by regulations. In the present case, the IUC Regulation, 2003 indicates by way of schedule the rate chargeable for a call originating from mobile to fixed, fixed to fixed, fixed to mobile etc. Under Section 13 of the 1997 Act, F^{TRAI is empowered to issue directions from time to time to the} service providers for the discharge of its functions under Section 11 (1) of the 1997 Act. As stated above, the classification of the three wireless services was done under the licence. The clarification issued by TRAI on 4.3.2005 was under Section 13 G^{of the 1997 Act. In the circumstances, the said clarification dated} 4.3.2005 was issued by TRAI in accordance with law.

Mr. Arun Jaitley, learned senior counsel for the appellant, on the issue of Unilateralism submitted that when the question - whether portable WLL(F) Phones should be B treated alike as WLL(M) phones was pending before TRAI pursuant to complaints from BSNL dated 4.1.2005, was it open to TRAI to issue a directive as is done in this case on 4.3.2005 without waiting for a Determination by the Competent Authority. In this connection reliance was placed on paras 2.26 and 2.27 of the Consultation Paper. We find^c no merit in this argument. As stated above, directive dated 4.3.2005 is clarificatory and not amendatory. The context in which the Consultation Paper emanated has been explained by us in our Judgment in the Civil Appeal of Reliance lnfocomm Ltd .. We do not wish to repeat the reasons herein once again. In any D event, we have looked into technology aspect and policy framework for levy of ADC hence there is no unilateralism as alleged by the appellant.

¶749

Before concluding, one aspect needs to be E mentioned. It is alleged by the appellants and also by Reliance lnfocomm Ltd. in the conjoint appeal which we will separately deal with in the subsequent judgment that BSNL have also not disclosed their numbering levels for their fixed wireless service and for their WLL(M) services which they F have been providing during the relevant period in the name of "Tarang", which according to the appellants, would now constitutes WLL(M) service. According to the appellants, BSNL has also been providing fixed wireless phone services which has limited mobility. This is a matter of quantification. That stage has not yet arrived. However, Mr. Gopal Subramanium, · G learned senior counsel appearing on behalf of BSNL, has fairly stated that BSNL would abide by the parameters laid down in our judgment and whatever adjustments required to be made in that regard in the context of claims and counter claims, the same shall be worked out in near future. Be that as it may, we express H
